NUT-LOCK.

Specification of Letters Patent.

Application led January 9, 1909.

Patented Aug. 17, 1909.

Serial No. 471,495.

' clear, and exact description of the invention,

Which-Will enable thers'skilled in the art to which it appertains to make and use the same, reference being had to the accompanylng drawings, which form part of this specili- Fig. l is a fragmentary detail of a bolt show- My invention relates to improvements in nut locks. A

The Aprima-ry object of iny-invention is to provide a cheap, simple and convenient nut locking device, so constructed as to be applied to a nut and bolt in any ordinary situation, and adapted to rigidly secure the nut against turning or getting loose even were all the threads to be stripped off, and adapted to rigidly secure the nut in position by a positive grip in use.

My invention consists of a flexible metal strap or clip adapted to have its ends iirinly united when embracing the periphery of the nut, and-is provided With a fined or integral pin bent to a right-angular relation with the axis of the nut, and adapted to pass through a diametric opening in the adjacent end of the bolt.

The novel feature of my invention resides inthe construction by Which it can be readily applied to the nut ina-ny possible position thereof With equal facility and convenience.-v

Similar reference Aiiuirierals indicate like parts throughout the several views iii 'Which- Figure 1 is a view oi the invention in position upon ahexagonal nut and the locking pin assed through a diametric opening in the yiiolt, partly breken away. Fig. 2 is a Vperspective view of 'a bolt and nut with my invention applied theireto.. Figs) 3, l:tand ."3 are plan, end, and sidiI views, respectivelji', of

aaiiodilied 'I'oi'm ol' my invention, the locking- .pin being 'loi-ined oi' a folded integral strip;

ing the form of diaiiietric opening lor the -lorin ol' locking pin shown in Figs.l 3,v 41 and 5. Figs. 7 and 8 are side views showing the arrangement of the invention oli-a foui'fsideijl .nut with theinterlocliing ends and locking pin in'ditlerent positions thereon. Fig. 9 is a sectional view showing a .niodiiied means for securing the ends of the. strap.

with the usual screw-threaded'portion 2 having a diainetric opening, either circular as shown at 3, in Fig. 1, or consisting of a longitudinal slot 4, Fig. 6. On the screw-threaded portion is mounted a. nut 5 preferably hexagonal, Figs. 1 and 2.

My invention consists of a sheet metal .strap @having a. transverse slit 7 at one end thereof, and having its other end provided 'with terminal tongue 8 having a width slightly less than t-he length of the said slit,

therewit i in ilse.`

The strap 6 has a laterally arranged in formed of two integral similarly bent parallel sheet inetal strips 10, of proper Width to pass through the slot 4 4in the screw-threaded portion of the bolt.

The operation'and manner of employing iny invention thus describedis obvious, and brieily stated is as follows: When the nut'5 has been properly tightened on the bolt 1 the strap 6 is bent to snugly lit the angular sides of the nut, and the pin 9 has its free end bent in right-angular relation with the portion 11 distance between the strap and the said diainetric opening in the bolt, after which the free. end of the pin 9 is inserted in the opening, and the strap is iirmly iiiteilocked at its ends by passing the .Longue 8 through the 'slot 7 and then folding it upon itself as shown in Figs. 3 and 4.

AIt .is obvious that when thus secured in position the nut can not turn or become loosened, and even were the threads of the bolt stripped oil, because the pin will prevent displacement ol' the nut.

ll'hen the bolt has av slot 4 instead of a round hole, the pin loi-ined ot' the strips 1() is inserted in the slot and the strap 6 is then bent to lit the angular sides of the nut as before,

,i and lthen its ends are interlocked as described,

andas shown iii Figs. 7 vand S.

lf prel'ei'rcd both ends of the strap 6 may be provided with transverse slits 12, Fig. 9,

The bolt 1. of any proper dimensions, and of any coinrnon form, has one-end provided and ada ted to form an interlocking unionl thereof substantially equal in length to the p Y and then united by means eta Ilexible nieta-lV 1. A nut lock consisting of a flexible sheetto t e axis of the nut.

2. The combination of a nut locking device consisting of a flexible sheet-metal stra for embracing the perighery of the nut, an( s, and provided with a fixed pin projecting from one edge of the v having interlocking en and having diametrlc opening to receive the said pm;

and a nut mounted on the bolt, all substantially as described.
